Adjustment of hydraulic weight transfer
Hydraulic weight transfer distributes the weight evenly between all roller sections.
1.
Once the roller is unfolded, relieve pressure in the extend/retract cylinders
(marked: Red), and activate cylinder control handle in the opposite direc-
tion.
Fig. 9
2 After short delay
the manometer will react.
Increase pressure to approx.
15
bar (A). This will trans-
fer some
of
the
mid-
section weight to the side sec-
tions.
3
Set control handle to flow setting. Flow setting is necessary to achieve hy-
draulic weight transfer, allowing the sections to move independently
4
The pressure for hydraulic weight transfer may need adjustment. It can al-
so be necessary to adjust pressure according to soil conditions.
Excessive pressure
1
Pressure on the side sections will be too great, leaving clear tracks in the
soil.
2
The mid-sections will not apply sufficient pressure, leaving the soil higher
and not as compressed as the sides.
Insufficient pressure
1
The pressure on the extremities of the side sections will be insufficient to
give uniform compression.
2
The mid-sections will compress too much, leaving the soil lower than the
sides.
To prolong service life and the final result in the field, MAXIROLL must be
set in
flow setting
when working in the field.
Failure to do so is incorrect use and can cause the frame to break in the
worst scenario.
